prep2007笔记 152题答案的疑问

Recent research indicates that two popular arthritis drugs are possibly not as safe as they initially
believed.
(A) that two popular arthritis drugs are possibly not as safe as they initially believed
(B) that two popular arthritis drugs may not be as safe as they were initially believed to be
(C) two popular arthritis drugs to possibly not be as safe as it was initially believed
(D) the safety of two popular arthritis drugs may not be as great as it was initially believed
(E) the safety of two popular arthritis drugs not to be as great as they were initially believed to be

答案是B. 我感觉A似乎更对一些.
笔记上的解释是：

(A) they没有指代对象，因为用的是主动语态they believed…，如果they指代drugs，则必须用被动语
态。
(B) 正确，that 引导宾语从句说明indicate 的内容，as 在这里的作用更类似连词，连接一个主句和一
个从句。

我感觉它的解释不是很正确. A选项的they可以指代drugs，后边的initially believed完全可以做一个-ed分词做drugs的定语啊.这样不就通了.they后面省略了be动词were；
B选项乍看一下，它的前后结构其实是不怎么平行的。前面是may not be 后边是 were believed to be

我有点乱，求NN们给个更好的分析解释吧，谢谢了

A的话they 指代的是drugs，所以用they believed的意思相当于是drugs believed，逻辑上是不合理的

如果照你说的，先拎句子主干： drugs are not as safe as they (believed），这个believed做分词修饰they，是修饰语。在分析句子主干时可以去掉。那么你看，这个句子是不是没有说完？

我看曼哈顿论坛上说的是they指代药的时候 是和to be链接，如果指代人的话，they believed 即可，所以a中指代的因该是药，是药的话应该就是 加上to be，b是对的，c中it 和drugs的单复数不一致 因该用 were 排除，d中应该是to be， e中应该是it 不是they，因为saftey是单数。 opening chat
